Tube and Finned Tube for Oil and Gas Processing
Gas treatment and oil processing plants sit in the worst atmospheres their own product creates - salt air, sour gas, heavy residues. Tube choice here is about what happens outside the tube as much as inside it.
What Fails First in Oil and Gas Processing
Base tubes corroding under the fins
Coastal and plant atmospheres attack exposed parent metal on wound fin tubes.
Sour service cracking
H2S bearing streams need corrosion resistant alloy tubulars, not carbon steel.
Heating heavy oil in storage
Viscous product needs extended surface that will not foul in axial flow.
Gas cooler bundles losing duty
Fin loosening in temperature cycling service.
Tube We Supply Into This Sector
Extruded Fin Tube
Bimetal tube with the fin extruded from an outer sleeve, giving a seamless fin-to-tube wall
Base tube diameter: 10 mm - 51 mm · Base tube wall thickness: 1.65 mm - 3.0 mm
"G" Embedded Fin Tube
Fin strip rolled into a machined groove in the tube wall for permanent metal-to-metal contact
Base tube diameter: 16 mm - 80 mm · Base tube wall thickness: 1.65 mm - 4.0 mm
Longitudinal Fin Tube
Straight fins welded along the tube axis for viscous fluids and low velocity gas
Base tube diameter: 12 mm - 273 mm · Base tube wall thickness: 2.11 mm - 25.4 mm
Nickel / Nickel Alloy Tube
Monel, Inconel, Incoloy and Hastelloy grade seamless tube for the hardest corrosion duty
Tube outside diameter: 1/2" - 3" (12 mm - 76.2 mm) · Tube wall thickness: 0.02" - 0.5" (0.5 mm - 12.0 mm)
Duplex Stainless Steel Tube
Duplex and super duplex seamless tube and pipe to ASTM A789 and A790
Tube outside diameter: 1/2" - 3" (12 mm - 76.2 mm) · Tube wall thickness: 0.02" - 0.5" (0.5 mm - 12.0 mm)Where It Goes
- Natural gas treatment coolers
- Compressor coolers and after-coolers
- Storage tank heating elements
- Sour service casing, tubing and coupling stock
How We Deliver Into This Industry
Where the enquiry is API 5CRA / ISO 13680, that requirement goes on the order at the start, because it changes the melt route and the testing, not just the paperwork.
Production runs on 25 rolling and cold drawing machines plus 23 fin lines and machines, with hydro, eddy current, mechanical and chemical testing performed in house. The company holds ISO 9001:2015, CE certificate, Production licence for pressure pipe and ships to the European, American and Gulf markets.

Oil and Gas Processing Questions
Why choose extruded fin tube for gas treatment coolers?
Because the aluminium sleeve covers the base tube along the finned length, so a salt-laden or chemical plant atmosphere never reaches the parent metal.
What tube heats a storage tank?
Longitudinal fin tube, on base tubes up to 273 mm. Straight fins keep outside pressure drop low and drain in the flow direction.
Do you supply sour service tubulars?
Yes, corrosion resistant alloy tube to API 5CRA / ISO 13680. State the requirement at enquiry stage because it changes the testing.
Can fin material differ from base tube material?
On mechanical fin types, yes - aluminium or copper fin on stainless, titanium, nickel or copper base tube.
